New Gear Break-In
All new gear sets require a Break-In Period
to prevent damage from overheating. After driving the first 15-20 miles it is best to stop and let the differential cool before
proceeding. Most manufacturer's warranty requires at least 500 miles before towing. We also require towing for very short
distances (less than 15 miles) and letting the differential cool before continuing during the 45 towing miles. This may seem
unnecessary but it is very easy to damage the differential by loading it before the gear set is completely broken in. We also
recommend changing the oil after the first 500 miles. This will remove any metal particles or phosphorus coating that has
come from the new gear set.
The
Greatest damage results when a new Ring & Pinion has been run for several miles during the first 500 miles and the oil
is very hot. Any heavy use or overloading at this time will cause irreparable damage to the grear set that can be determined
by the inspection of the gear set and will not be warranted by Southern Gear Company, Inc.
ANY OVERLOADING OR OVERHEATING WILL CAUSE THE GEAR
OIL TO BREAK DOWN AND THE RING & PINION TO FAIL.
POSITRACTIONS
Positraction chatter
in normal for limited slip and positraction differentials. Both rear tires must measure the same height from the ground to
the top of the wheel in order for the differential to function properly without premature wear. Limited slip additive or friction
modifier for limited slip differentials must be used with the oil to reduce positraction chatter in the event that the oil
is changed.
Lockers
Mechanical locking differentials will bang and cluck during normal operation. Both rear tires
must measure the same height from the ground to the top of the wheel in order for the top of the wheel in order for a
locking differential to function properly.
Gear Noise
Richmond Gear and other aftermarket (non OEM) gears are designed primarily for strength and may
be noisy. This noise is especially inherent in vans and quiet passenger cars.
